vnode_pager_putpages hanged my machine

Hi,

This is one of my first crashes of FreeBSD on my PC. Having lots of faith in
this OS, I still think it's one too many :).

While using ImageMagick's convert (as a user, NOT as root!), to generate an
mpeg file from a bunch of tiff files, my machine went bezerk (gradually slowed
down until no response at all anymore) and I had to hit PC's reset button to
reboot.

Did the machine end up in an eternal loop and ate up all resources?
A bug in vnode? Or in the pager?

My kernel and world update is from last week, Wed. March 3rd.
All other software is up-to-date with today's ports.

After reboot, I found this in /var/log/messages, before the reboot messages:

Any idea what caused this system breakdown?

It looks like convert was killed because it ran your machine out
of memory - that might explain extream slugishness if everything
else had been swapped out. It also looks like /var was completly
full.

Seems pretty obvious, you're /var file system if either too small, or
totally
overloaded. Something tried to use /var for storage of temporary data and 
couldn't put it there. Delete old logs you don't need, and if /var is
not
atleast 256MB, consider moving it to another disk or reinstalling with a 
larger /var.

Hope this helps
Will
